A potential predecessor to the Swedish flag with the Nordic cross could be the coat of arms of Sweden, introduced during the reign of King Charles VIII in 1448. The national coat of arms is a combination of King Albert's coat of arms of 1364 and King Magnus III's coat of arms of 1275, and is blue divided quarterly by a golden cross pattée. Other ideas claim that the Swedish flag was blue with a white cross before 1420, and became blue with a golden cross a century later during the early reign of King Gustav I.[citation needed]
